Antioxidant enzyme and inflammation marker mRNA expression modulation in keratinocytes exposed to pristine and aged InZnP quantum dots (QDs). Quantitative reverse transcription PCR (RT-qPCR) analysis of mRNA expression of antioxidant enzymes (A) and inflammation markers (B) in cells exposed for 24 h to 25 nM pristine QDs, 6.25 nM of aged QDs, 50 μM of In(III)-acetate, or 50 μM of Zn(II)-acetate. Data are mean ± standard deviation of three biological replicates (two technical replicates), on keratinocytes from a single human donor. Statistical significance: p ≤ 0.05, *exposed vs. control.
